Abstract
Systems and methods are provided and include an optical sensor configured to be disposed on a sight glass. The optical sensor is configured to generate signals based on a light reflectivity associated with a liquid of the refrigeration system. An optical sensor control module that includes a processor that is configured to execute instructions stored in a nontransitory memory, and the instructions include (i) generating a set of data based on the signals, and (ii) determining an amount of liquid of the refrigeration system based on the set of data.
